In con_work(), when BACKOFF is set, if queue_delayed_work() doesn't result in newly-queued work, it simply ignores this condition and proceeds as if no backoff delay were desired. There are two problems with this--one of which is a bug. The first problem is simply that the intended behavior is to back off, and if we aren't able queue the work item to run after a delay we're not doing that. The only reason queue_delayed_work() won't queue work is if the provided work item is already queued. In the messenger, this means that con_work() is already scheduled to be run again. So if we simply set the BACKOFF flag again when this occurs, we know the next con_work() call will again attempt to hold off activity on the connection until after the delay. The second problem--the bug--is a leak of a reference count. If queue_delayed_work() returns 0 in con_work(), con->ops->put() drops the connection reference held on entry to con_work(). However, processing is (was) allowed to continue, and at the end of the function a second con->ops->put() is called. This patch fixes both problems.

The rt_gateway checks in H.323 helper try to avoid the creation of an unnecessary expectation in this call-forwarding case: http://people.netfilter.org/zhaojingmin/h323_conntrack_nat_helper/#_Toc133598073 However, the existing code fails to avoid that in many cases, see this thread: http://marc.info/?l=linux-netdev&m=135043175028620&w=2 It seems it is not trivial to know from the kernel if two hosts have to go through the firewall to communicate each other, which is the main point of the call-forwarding filter code to avoid creating unnecessary expectations.

charset=UTF-8 Content-Transfer-Encoding: 8bit The overlay on the i830M has a peculiar failure mode: It works the first time around after boot-up, but consistenly hangs the second time it's used. Chris Wilson has dug out a nice errata: "1.5.12 Clock Gating Disable for Display Register Address Offset: 06200h–06203h "Bit 3 Ovrunit Clock Gating Disable. 0 = Clock gating controlled by unit enabling logic 1 = Disable clock gating function DevALM Errata ALM049: Overlay Clock Gating Must be Disabled: Overlay & L2 Cache clock gating must be disabled in order to prevent device hangs when turning off overlay.SW must turn off Ovrunit clock gating (6200h) and L2 Cache clock gating (C8h)." Now I've nowhere found that 0xc8 register and hence couldn't apply the l2 cache workaround. But I've remembered that part of the magic that the OVERLAY_ON/OFF commands are supposed to do is to rearrange cache allocations so that the overlay scaler has some scratch space. And while pondering how that could explain the hang the 2nd time we enable the overlay, I've remembered that the old ums overlay code did _not_ issue the OVERLAY_OFF cmd. And indeed, disabling the OFF cmd results in the overlay working flawlessly, so I guess we can workaround the lack of the above workaround by simply never disabling the overlay engine once it's enabled. Note that we have the first part of the above w/a already implemented in i830_init_clock_gating - leave that as-is to avoid surprises. v2: Add a comment in the code.

Shuts up annoying warnings from the modeset-rework, too. I've noticed that with this patch we know get and unknown connection state since the code can't find a suitable pipe for load detection. But that beats the previous state of affairs, where it tried to use pipe B, actually used pipe A and concluded that something is connected (although it's the LVDS on pipe A and nothing on the VGA connector on pipe B). I've tried to make load detect work by remapping the pipe->planes stuff, so that crtc 0 will use pipe B and hence we still have something left for load-detect on pipe A. But alas, that upset the hw a bit. So there's still some things to figure out, but this here will at least paper over some of the problems.

Unfortunately, this last part was not done until now, causing for example the LEDs to not be properly set to their default initial value. This patch fixes this by calling the mvebu_gpio_set() function from mvebu_gpio_direction_output() before configuring the GPIO as an output GPIO.

Since infoframe buffer writing is now a bit more elaborate, extract it into it's own function. This will be useful if we ever get around to properly update the ELD for sdvo. Also #define proper names for the two buffer indexes with fixed usage. v2: Cite the right commit above, spotted by Paulo Zanoni. v3: I'm too stupid to paste the right commit. v4: Ben Hutchings noticed that I've failed to handle an underflow in my loop logic, breaking it for i >= length + 8. Since I've just lost C programmer license, use his solution. Also, make the frustrated 0-base buffer size a notch more clear.

When flushing plug-list,because elv_attempt_insert_merge only support backmerge,not supporting frontmerge. So rq[7493120 + 24] can't merge with rq[7493144 + 104]. From my test,i found those situation can count 25% in our system. Using this patch, there is no this situation.

The first hexadecimal digit shall be the most significant four bits of the first byte (i.e., most significant byte) of the EUI-64 based identifier; b) the four UTF-8 characters 'naa.' concatenated with 16 or 32 hexadecimal digits for an NAA identifier (see 7.8.6.6). The first hexadecimal digit shall be the most significant four bits of the first byte (i.e., most significant byte) of the NAA identifier; or c) the four UTF-8 characters 'iqn.' concatenated with an iSCSI Name for an iSCSI-name based identifier (see iSCSI). However, the .tpg_get_wwn method for tcm_qla2xxx formats the WWN so the SCSI name string looks like "52:4a:93:7d:24:5f:b2:12,t,0x0001". This patch corrects the code so that VPD 83h gives a SPC-compliant SCSI name string like "naa.524a937d245fb212,t,0x0001" while leavig other uses alone (so configfs will still work with ':' separated WWNs).

However, the session structures are stored in tables that are indexed by these two keys, and if we just change the session structure but leave the pointers to it in the old places in the table, havoc can ensue. For example, a new session might come along that should go in the old slot in the table and overwrite the old session pointer. To handle this, add a new tgt_ops->update_sess() method that also updates the "by loop_id" and "by s_id" lookup tables when a session changes, so that the keys where a session pointer is stored in these tables always matches the keys in the session structure itself.

This is done as some fabrics expect TMR operations to be acknowledged before releasing the descriptor, so the assumption that core is releasing se_cmd associated TMR memory is incorrect.

There are still clients out there which use these old SCSI-2 commands. This mainly happens when running VMs with legacy guest systems, connected via SCSI command pass-through to iSCSI targets. Make them happy and return status GOOD. Many real SCSI disks or external iSCSI storage devices still support these old commands. So let's make LIO backward compatible as well.

The title has been updated slightly to reflect (what should be) the final fix. When a GPIO is freed or shutdown, we need to ensure that any debounce settings are cleared and if the GPIO is the only GPIO in the bank that is currently using debounce, then disable the debounce clock as well to save power. Currently, the debounce settings are not cleared on a GPIO free or shutdown and so during a context restore on subsequent off-mode transition, the previous debounce values are restored from the shadow copies (bank->context.debounce*) leading to mismatch state between driver state and hardware state. This was discovered when board code was doing gpio_request_one() gpio_set_debounce() gpio_free() which was leaving the GPIO debounce settings in a confused state. If that GPIO bank is subsequently used with off-mode enabled, bogus state would be restored, leaving GPIO debounce enabled which then prevented the CORE powerdomain from transitioning. To fix this, introduce a new function called _clear_gpio_debounce() to clear any debounce settings when the GPIO is freed or shutdown. If this GPIO is the last debounce-enabled GPIO in the bank, the debounce will also be cut. Please note that we cannot use _gpio_dbck_disable() to disable the debounce clock because this has been specifically created for the gpio suspend path and is intended to shutdown the debounce clock while debounce is enabled. Special thanks to Kevin Hilman for root causing the bug. This fix is a collaborative effort with inputs from Kevin Hilman, Grazvydas Ignotas and Santosh Shilimkar. Testing: - This has been unit tested on an OMAP3430 Beagle board, by requesting a gpio, enabling debounce and then freeing the gpio and checking the register contents, the saved register context and the debounce clock state. - Kevin Hilman tested on 37xx/EVM board which configures GPIO debounce for the ads7846 touchscreen in its board file using the above sequence, and so was failing off-mode tests in dynamic idle. Verified that off-mode tests are passing with this patch.

Nix ran into this when using the journal_async_commit mount option, which enables journal checksumming. The ensuing journal replay failures due to the bad checksums led to filesystem corruption reported as the now infamous "Apparent serious progressive ext4 data corruption bug" [ Changed by tytso to only call ext4_journal_get_write_access() only when we're fairly certain that we're going to allocate the inode. ] I've tested this by mounting with journal_checksum and running fsstress then dropping power; I've also tested by hacking DM to create snapshots w/o first quiescing, which allows me to test journal replay repeatedly w/o actually power-cycling the box. Without the patch I hit a journal checksum error every time. With this fix it survives many iterations.

Besides the leak, other side effect in the current code is if blk_init_queue fails, we would end up calling unregister_blkdev even if we didn't call yet register_blkdev. Just moved the allocation of floppy_wq before the loop, and adjusted the code accordingly.

This causes test runs to immediately stop. Over the past 6 or 7 years we've added hacks like explicit unmount -d commands for loop mounts, losetup -d after unmount -d fails, etc, but still the problems persist. Recently, the frequency of loop related failures increased again to the point that xfstests 259 will reliably fail with a stray loop device that was not torn down. That is despite the fact the test is above as simple as it gets - loop 5 or 6 times running mkfs.xfs with different paramters: lofile=$(losetup -f) losetup $lofile "$testfile" "$MKFS_XFS_PROG" -b size=512 $lofile >/dev/null || echo "mkfs failed!" sync losetup -d $lofile And losteup -d $lofile is failing with EBUSY on 1-3 of these loops every time the test is run. Turns out that blkid is running simultaneously with losetup -d, and so it sees an elevated reference count and returns EBUSY. But why is blkid running? It's obvious, isn't it? udev has decided to try and find out what is on the block device as a result of a creation notification. And it is racing with mkfs, so might still be scanning the device when mkfs finishes and we try to tear it down. So, make losetup -d force autoremove behaviour. That is, when the last reference goes away, tear down the device. xfstests wants it *gone*, not causing random teardown failures when we know that all the operations the tests have specifically run on the device have completed and are no longer referencing the loop device.

The spots to put bandaids are: - PCM prepare, hw_params and hw_free - where the usb device is accessed for communication or get speed, in mixer.c and others; the device speed is now cached in subs->speed instead of accessing to chip->dev The accesses in PCM open and close don't need the mutex protection because these are already handled in the core PCM disconnection code. The autosuspend/autoresume codes are still uncovered by this patch because of possible mutex deadlocks. They'll be covered by the upcoming change to rwsem. Also the mixer codes are untouched, too.

The client will then answer using a normal Ack instead of a BlockAck. This acknowledgement has no TID stored and therefore the hardware is not able to provide us the corresponding TID. The TID set by the hardware in the tx status descriptor has to be seen as undefined and not as a valid TID value for normal acknowledgements. Doing otherwise results in a massive amount of retransmissions and stalls of connections. Users may experience low bandwidth and complete connection stalls in environments with transfers using multiple TIDs.

The driver has its own implementation of these functions, which can pick the correct register depending on the CPU being used. The functions do however use the gc->mask_cache value. The call to irq_setup_generic_chip() was passing IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be initialized to the contents of some random register.

But if user requests dpms mode operation, OFF -> ON, when crtc's dpms callback is called, exynos_encoder->dpms is also changed to ON. This makes encoder's dpms callback call be ignored so display power couldn't become on again. This patch removes exynos_encoder->dpms changing and adds 'updated' variable to exynos_drm_encoder structure to avoid duplicated overlay updating.

As Mukesh explained it, the MMUEXT_TLB_FLUSH_ALL allows the hypervisor to do a TLB flush on all active vCPUs. If instead we were using the generic one (which ends up being xen_flush_tlb) we end up making the MMUEXT_TLB_FLUSH_LOCAL hypercall. But before we make that hypercall the kernel will IPI all of the vCPUs (even those that were asleep from the hypervisor perspective). The end result is that we needlessly wake them up and do a TLB flush when we can just let the hypervisor do it correctly. This patch gives around 50% speed improvement when migrating idle guest's from one host to another.

The DNS resolver's use of the sunrpc cache involves a 'ttl' number (relative) rather that a timeout (absolute). This confused me when I wrote commit c5b29f885afe890f953f7f23424045cdad31d3e4 "sunrpc: use seconds since boot in expiry cache" and I managed to break it. The effect is that any TTL is interpreted as 0, and nothing useful gets into the cache. This patch removes the use of get_expiry() - which really expects an expiry time - and uses get_uint() instead, treating the int correctly as a ttl. This fixes a regression that has been present since 2.6.37, causing certain NFS accesses in certain environments to incorrectly fail.

The problem is the mount system call returns EIO which causes the mount to fail, instead of ETIMEDOUT, which would cause the mount to be retried. This patch sets the RPC_TASK_SOFT|RPC_TASK_TIMEOUT flags to the rpc_call_sync() call in nfs_mount() which causes ETIMEDOUT to be returned on timed out connections.

In practice this can kill an iSCSI connection if for example an initiator does single-threaded writes and the target misses the wakeup window when queueing an R2T; in this case the connection will be stuck until the initiator loses patience and does some task management operation (or kills the connection entirely). Fix this by converting to wait_event_interruptible(), which does not suffer from this sort of race.

The Radeon driver uses the analog/digital flag to determine if the DAC or the TMDS encoder should be enabled on a DVI-I connector. If the EDID is bogus this flag is no longer reliable. This fix adds a fallback to DAC load detection to determine if anything is connected to the DAC. If not and a (bogus) EDID is found it assumes a digital display is connected. This works around problems with some crappy IPMI devices using Radeon ES1000.

The division by zero occur in tcp_illinois_info() at: do_div(t, ca->cnt_rtt); where ca->cnt_rtt can become zero (when rtt_reset is called) Steps to Reproduce: 1. Register tcp_illinois: # sysctl -w net.ipv4.tcp_congestion_control=illinois 2. Monitor internal TCP information via command "ss -i" # watch -d ss -i 3. Establish new TCP conn to machine Either it fails at the initial conn, or else it needs to wait for a loss or a reset. This is only related to reading stats. The function avg_delay() also performs the same divide, but is guarded with a (ca->cnt_rtt > 0) at its calling point in update_params(). Thus, simply fix tcp_illinois_info(). Function tcp_illinois_info() / get_info() is called without socket lock. Thus, eliminate any race condition on ca->cnt_rtt by using a local stack variable. Simply reuse info.tcpv_rttcnt, as its already set to ca->cnt_rtt. Function avg_delay() is not affected by this race condition, as its called with the socket lock.

Originally, only PIOQUEUE was supported and it had issues, then DMA support was added this cycle. The original intention was to keep PIOQUEUE since it has less overhead what is nice for small transfers. However, runtime switching between PIOQEUE and DMA depending on the transfer size never worked despite a lot of trying. Since PIOQUEUE mode itself was flaky (polling at places where interrupts failed to work) and the implementation also imposed a size limit for transfers, it is best to remove the support, so users don't fall over its limitations. It also makes the driver a lot cleaner and more robust. If somebody really wants less overhead, plain PIO mode could still be implemented with the addidtional advantage that this mode is also available on MX23, too.

Unfortunately up to this moment input devices did not provide support for managed devices and that lead to mixing two styles of resource management which usually introduced more bugs, such as manually unregistering input device but relying in devres to free interrupt handler which (unless device is properly shut off) can cause ISR to reference already freed memory. This change introduces devm_input_allocate_device() that will allocate managed instance of input device so that driver writers who prefer using devm_* framework do not have to mix 2 styles.
